Study summary

While people commonly understand that regular physical exercise conveys many health benefits, only 20% of U.S. adults take regular exercise and they have difficulty maintaining new healthy behaviors. The goal of this study is to use a planning intervention to help establish and maintain a daily step regimen in working midlife adults. The investigators will ask participants to plan when, where, and how to act on a daily walking goal in conjunction with a scheduling intervention to increase the chances that they will maintain this new regimen. The effectiveness of three different scheduling interventions will be compared.

Read the detailed description

While people commonly understand that regular physical exercise conveys many health benefits, only 20% of U.S. adults take regular exercise and they have difficulty maintaining new healthy behaviors. The goal of this study is to use a planning intervention to help establish and maintain a daily step regimen in working midlife adults. The investigators will ask participants to plan when, where, and how to act on a daily walking goal in conjunction with a scheduling intervention to increase the chances that they will maintain this new regimen. Participants will be randomly assigned to one of three conditions: consistent schedule, inconsistent schedule, no schedule. All participants will be provided with an accelerometer to measure their daily activity and as a behavioral support for our intervention and they will be given a step goal. The goal given to each individual will be to increase immediately their daily steps to a level based on recommended guidelines (e.g., Hill, Wyatt, Reed, and Peters, 2003). The investigators will test which version of the scheduling intervention is most successful for increasing and maintaining step counts. It is predicted that participants in the consistent schedule condition will increase their step count more than those participants in the no schedule control condition, and that they will maintain this activity for a longer period after the intervention period is complete than those participants in the inconsistent schedule condition.

Study arms

  • Active comparator
    No schedule control

    This group will receive an accelerometer and daily step goal. They will monitor their steps over the 9 week duration of the study. They will also monitor their steps over the 9 week duration of the study. They will have the same level of contact as the other two conditions.

    Device: Accelerometer · Behavioral: Step goal

  • Experimental
    Consistent schedule condition

    This group will receive an accelerometer and daily step goal. They will monitor their steps over the 9 week duration of the study. They will have the same level of contact as the other two conditions. In addition they will plan when, where, and how they will take steps in consistent contexts, i.e., that are very similar from day to day.

    Inconsistent schedule condition

    This group will receive an accelerometer and daily step goal. They will monitor their steps over the 9 week duration of the study. They will have the same level of contact as the other two conditions. In addition they will plan when, where, and how they will take steps in inconsistent contexts, i.e., that vary from day to day.

What researchers measure

Primary outcomes

  1. Physical activity

    Number of steps taken each day as measured on accelerometer

    Time frame: Daily for 9 weeks

Secondary outcomes

  1. Measures of well being

    Feelings of satisfaction with life, perceived stress, mood and sleep quality

    Time frame: Before and after intervention (5 weeks apart), and at followup (4 weeks later)

  2. Physical activity self-efficacy and ease

    Perceived ability and ease of being physically active

    Time frame: Weekly for 4 weeks

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Apr 2018 to primary completion in Jul 2019, 15 months.

Of 5,147 non-industry interventional studies with no phase under Motor Activity, half reached primary completion within 17 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 36. This study's 15 months is below that.

Counting every sponsor, half of 5,207 studies reached it within 17 months; a quarter within 7 and three quarters within 36.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 17, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
